I'm going to fill in the design with a bit of boxwood greenery. I love the smaller leaves and the tiny laterals coming off the main stem.
I'm going to insert some sprigs at an angle on both sides of the arrangement.
I also tucked in a bit in the back of the design to help cover up the foam and any signs of the florist clay.
You can see that the mixture of various greens and flowers are filling in nicely and concealing all signs of our mechanics.
